So we should be able to build an internal glibc toolchain for nios2 now. * Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions. The original MIPS o32 hard-float ABI requires an FPU where double-precision registers overlay two consecutive single-precision registers. MIPS32R2 introduced a new FPU mode (FR=1) where double-precision registers extend the corresponding single-precision registers which is incompatible with the o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both require the use of FR=1 making a transition necessary. New o32 ABI extensions enable users to migrate over time from the original o32 ABI through to the updated o32 FP64 ABI. To achieve this the dynamic linker now tracks the ABI of any loaded object and verifies that new objects are compatible. Mode transitions will also be requested as required and unsupportable objects will be rejected. The ABI checks include both soft and hard float ABIs for o32, n32 and n64. I'm not sure what the impact is of this exactly? -- Bye, Peter Korsgaard
